Stuck in a party

Hello,

so I turn the WoW on today and I realised that I am stucked in party. BUT! There is no other member in the party. So I am alone in party which is weird and I cant leave the party, cause there is no option. I cannot go to another party, no one can invite me and I cant join RDF. If I click on join rdf this is being said: Other member is waiting for invitation or something like that. Could you please fix it? Thank you.

type this:
/script LeaveParty()

Thank you very much it is finally solved. Thank you
